Dave Wise All Messages By This Member #204893 I don't know which scope used compactrons. I do know a cal fixture sort of did. From my notes: Tektronix 067-0502-01 Amplitude Calibrator. The voltage regulator originally used the 6GE8/7734 signal pentode/power triode, but later switched to the 6G11 signal pentode/beam power tube, triode-connected in a purpose-built adaptor. Besides the 12BU pinout (6AL11 and 6G11) the adaptor is made for, the 12EZ tubes (6AD10 6BF11 6BY11 6T10) can probably work, with a new adaptor.

Tom Lee All Messages By This Member #204894 Thank you, Dave. I’m wondering whether that 6C10 was used in a production instrument or an in-house fixture. I just checked the web and it commands crazy prices on eBay. Audiophiles have clearly fallen in love with its triple-triode sonic magic.

Dave Wise All Messages By This Member #204905 You're welcome, Tom, but I can't claim knowledge here, I just looked it up in the manual. I am pretty good at that. ?

greenboxmaven All Messages By This Member #204924 6C10s are three 12AX7 sections in one envelope. For many applications, the 6AC10 will work fine, it's three 12AU7 sections in one envelope. Not only do the AudioPhools like them, guitar amplifier builders are smitten too, and many hifi amplifiers and tuners use them. Compactrons were a last ditch effort to reduce vacuum tube overall cost and size, and buy time for developing solid state equipment. For this reason, they tend to be more rugged and longer lasting so people won't be? so annoyed at replacing them when only one section has failed. ??

Charles, WB3JOK/0 Member Profile All Messages By This Member #204932 The 6AC10 has an amplification factor of 62 for each section (like a 12AT7). The 6C10 is 100, as you pointed out, like a 12AX7. They work perfectly in a Heath HO-10, probably in other instruments, and are around $7 instead of $100 to $200 (ridiculous)... -Charles
Joel B Walker All Messages By This Member #204933 The Type 549 uses a 6GF5 in the HV supply, also the "almost" compactron 8608 in the vertical output section.
